Abstract
PURPOSE: The gas phase polymerization of vinyl chloride is conducted by using a vinyl chloride polymer prepared by bulk polymerization in the presence of a cellulose derivative as a seed polymer to produce a polymer with uniform particle sizes without any lost of the advantage of gas phase polymerization.
